Abstract (en)

The device has a notch filter (30) that receives an input signal (INCOS) containing useful and noise signals and generates a filtered signal. The notch filter center frequency corresponds roughly to the input signal frequency to suppress at least part of the useful signal. A mixer circuit receives the filtered signal and a phase-shifted input signal and outputs a demodulated output signal (OMPXA) substantially corresponding to the noise signal AN Independent claim is also included for the following: a demodulator circuit with a bandpass filter circuit and an anti modulator circuit.
